Mishkat al-Masabih 17 Prescribed Punishments كتاب الحدود 73

وَعَنْ أَنَسٍ قَالَ: لَقَدْ حُرِّمَتِ الْخَمْرُ حِينَ حُرِّمَتْ وَمَا نَجِدُ خَمْرَ الْأَعْنَابِ إِلَّا قَلِيلًا وَعَامة خمرنا الْبُسْر وَالتَّمْر. رَوَاهُ البُخَارِيّ

Anas said: Wine was forbidden when it was forbidden (i.e. by the Qur’an), but we get only a little of the wine from grapes, most of our wine being from unripe dates and dry dates. Bukhari transmitted it.
